I have a doubt regarding the use of fractal trees index in my tables. I create table specifing the TokuDB engine
CREATE TABLE `My_table` (
...
) ENGINE=TokuDB
Documentation says: "TokuDB uses a particular data structure called fractal trees, which is optimized for data that do not entirely fit memory."
But if I perform this query
SHOW INDEX FROM `My_table`
all indexes retreived for my table have index_type = BTREE
So... ...is this correct?
